Andreas Kling b01ce45c14 LibWeb: Guard non-subject pseudo-class invalidations 
Compound selectors with a non-rightmost pseudo-class used to register
their descendant and sibling invalidation plans directly under the
pseudo-class property. A selector like `.item:hover * .target` ran
the descendant plan for every hovered element, even when that element
could not match `.item`.

Store those non-rightmost plans behind a guard made from stable class
and id subject features in the same compound selector. Deliberately
leave pseudo-classes out of guards, since one mutation can change
multiple state pseudo-classes at once. Also leave tag and attribute
selectors out, since their matching depends on document and namespace
case-sensitivity that the guard property does not carry.

The new style-invalidation test covers the GitHub-shaped
`:hover * :not(...)` case, co-invalidated `:link` and `:any-link`,
partial or complex `:is()`/`:where()` alternatives, and case-sensitive
SVG tag and attribute selectors.
